Ok, I cut ‘The End’ a lot of slack for its indeterminate conclusion and unanswered questions. However, “Lemony Snicket: The Unauthorized Autobiography” is basically just Daniel Handler going “nyah nyah nyah readers: these are all the questions that I know I didn’t answer, enumerated – and I’m still not going to answer them! PSYCH!”
It doesn’t have a plot, and it’s not a biography, auto- or otherwise.
However, if you read all 13 Unfortunate Events, you might as well read this one too – it’s part of the same work, as a whole. And it is kind of cool, actually. But still.
